dc.description.abstract	The new Z' gauge boson is one of the consequences of some physics Beyond the Standard Model. Such a particle can emerge from a gauge extension of the Standard Model by an additional U(1) symmetry. We are interested in a U(1)x gauge extension, attached with a Stueckelberg way of attaining the mass of the new Z' boson. The Stueckelberg mechanism is characterized by the scalar σ, which obeys specific gauge transformations, ensuring the gauge invariance. It can be used as an alternative to the spontaneous symmetry breaking mechanism by extending the Higgs sector. This model is grounded in the choice taken for eliminating the unphysical bilinear terms, as well as the choice of the gauge fixing term. The impact of this Stueckelberg Z' is investigated in the context of "bb → vi" scattering process. Key words: BSM, U(1) extension of the SM, Stueckelberg mechanism, Z' gauge boson.	fr_FR
